Adjusting the Ribbon Sensor Sensitivity
The Ribbon Sensor system detects the presence of a ribbon in the system. The
Media Type parameter value determines how the printer uses the sensor (see
Media Settings section, Setting the Printing Method). In Direct
Thermal mode, the printer uses the sensor to verify a ribbon is not installed. In
Thermal Transfer mode the printer uses the sensor to detect the ribbon
installation and the trailer when the ribbon supply is empty. Follow the
procedure based on the type of problem reported by the printer.
Printer Displays “Remove Ribbon” Message in Direct Thermal Mode
The printer displays this message when Ribbon Sensor sensitivity level is less
than required. The Ribbon Sensor is not receiving light reflecting from the
back of the printhead bracket. Resolving this issue involves raising Ribbon
Sensor Sensitivity to a level that will allow the sensor to detect the reflective
material on the back of the printhead bracket. (Note: If current sensitivity
value accommodated a ribbon in Thermal Transfer mode, note the Ribbon
Sense parameter before the adjustment. This value will be required if using
the printer in Thermal Transfer mode at a later time.)

procedure again.
If this procedure fails to produce a working sensor sensitivity that stops the
Remove Ribbon messages contact qualified service personnel.
